Re: F103 dual channel wideband controller + EGT + 2 x AUX In + 2 Aux out

that is yet another good question, and if 10degC is enough, probably it won't matter what sort of connector you use ;-)

Re: Software knock processing

Thanks a lot! The only question is there are no PF4/PF5 pins in stm32f407vgt6 - there is no PF port at all. Is software knock processing at all supported in 407 chip?

Re: Software knock processing

so, do I get it right that the hip9011 solution has now become officially obsolete in rusefi? in this thread there are two almost similar schemes - with mcp6004 and with two LMV321IDBVR - which one is better? where do I get the Vmid (VREF2) signal and what to which pin of stm32f407 should i connect ...

Re: STM32F407VET6 Mini Development Board System Board

late followup. I just started the recent rusefi image on this board! (used jlink to flash it, had to solder on a 3k pull-up to pa12). I was surprised to see a usb disk with probably useful stuff)

Re: F103 dual channel wideband controller + EGT + 2 x AUX In + 2 Aux out

finding the proper connector for the thermocouple of a certain type is a quest in itself. however, if you look at cheap thermocouple plugs used in some multimeters - you might think there is nothing special in them - the wire's end forms a loop, which is just fixed to the plug with a screw. but you ...

Re: Proteus custom analog inputs

in mazda rx7 there are two fuel level sensors: the main one and the auxiliary one (the fuel tank is somewhat split, afaik), and they are not in series, but are rather connected to separate inputs in the dashboard.

Re: HOWTO use Bluetooth module

okay. don't know how to comment on github. The bluetooth module in alphax is definitely a BLE device (bursts of data, rather than old-style SPP profile) After you connect it to the MCU, (MCU's TX to WL9981TC RX, MCU's RX to WL's TX, Paragraph 4 of the datasheet), after power up you should see 'READY...

Re: HOWTO use Bluetooth module

nrf5822?

From my understanding, with alphax, you need first to flash "serial to BT" firmware to that chip (before soldering it onto the board). Then you'll need some special software supporting BLE on the PC side.
my bad. just found the datasheet on jlcpcb. will comment later.

Re: GD32 version of Wideband Controller

segger worked just fine for me with 190, but you'd probably have to reflash your stlink into jlink (google for that free reflash tool, the operation is reversable)
btw, with segger you'd have to choose the proper µcu.

Re: MRE addon Board - Wideband controller + SD Card slot + EGT Chip

are you going to use the ready-made firmware, or develop your own one?
afaik, there are no these chips available on jlcpcb, so you can't order assembly. meanwhile, there are still some GD32F190C8T6 left (5V adc and dac!), but they'd probably require some changes in the board layout.

Re: MRE addon Board - Wideband controller + SD Card slot

with native can bus support onboard, everything else looks excessive :D
however, to eliminate communications delays, may be other protocols would be more preferable (pure DAC-ADC? PWM-modulated? SPI?)
